How can I have a custom 404 page using Middleman? - middleman

I have followed all documentation guides, so I have the following line in my config.rb
page '/404.html', directory_index: false
Also, I have a source/404.html.erb page. I'm not sure what I'm I doing wrong, I am only able to see the File not found error page generated by default.
Thanks

I managed to solve the problem, what I did was:
In my Config.rb
I left this at global level **page '/404.html'**, layout: 'error'
Removed this activate :relative_assets
In production and staging blocks I modified error document to s3_sync.error_document = '404/index.html', this was the cause why I was losing my assets as once the site has been deployed 404.html does not exist anymore, I was pointing to the wrong error_document
I created a separate layout called error as suggested on this thread for my 404 page.
I am using
'middleman', '~> 4.1', '>= 4.1.10'
'middleman-s3_sync', '~> 4.0', '>= 4.0.2'
"webpack": "~3.5.5"
Hope this help somebody else in the same issue.

Rails Missing Template On Production Server

Before I start, I'd like to stress that I've looked for answers and I've tried to solve the issues by myself.
I have 2 types of controllers -
A controller with a set of methods that render JSON - works perfectly
A controller that actually renders HTML
This code is working perfectly on my local machine and the problem that I have with the second controller is on my production machine.
I've added 755 permissions to all my files but my file owner is the only user on my server which is "root". I've added the files to the www-data group though.
My controller is simple.
class AdministratorController < ApplicationController
def login
end
end
And my file is views/administrator/login.html.haml.
I'm getting an error -
ActionView::MissingTemplate (Missing template administrator/login, application/login with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder]}. Searched in:
* "/var/www/sitename/app/views"
):
Try to add to your Gemfile
gem 'haml-rails'
And run bundle install.
The issue has been resolved. I'm not sure what exactly went wrong with the template but I began seeing a different error relating to compiled assets. I just recompiled the assets and restarted the server. Thanks for all your help!

How to set sinatra-authentication to use erb instead of haml?

I'm trying to set up the sinatra-authentication gem in a simple sinatra app, and running into an issue where sinatra can't find the correct views. I understand that sinatra-authentication uses haml by default, but I'm using erb in this app.
This in mind, I found in the sinatra-authenticaiton docs that there is a setting which allows you to change the template engine, by adding the following to your app file:
configure do
set :template_engine, :erb # for example
end
I've added this to my app.rb file, and sinatra is still looking for the signup.haml when I try to hit the /signup route in my app.
A couple of notes:
I've included the gem in my Gemfile, and successfuly run a bundle install on my app.
source 'https://rubygems.org'
gem 'sinatra'
gem 'data_mapper'
gem 'pg'
gem 'dm-postgres-adapter'
gem 'sinatra-authentication'
I saw something in the documentation that suggested that I may need to specify the location of my view files, so I added the following to my configuration block.
set :sinatra_authentication_view_path, Pathname(__FILE__).dirname.expand_path + "views/"
**I think I've required the gem accurately in my app file by adding
require "sinatra-authentication"
use Rack::Session::Cookie, :secret => 'mys3cr3tk3y'
This gist is a current representation of my app.rb file in the root of my sinatra app. https://gist.github.com/rriggin/5378641#file-gistfile1-txt
Here is a screenshot of the error sinatra throws: http://cl.ly/image/0y041t0K3u3O
When I run the app locally, a 'dm-users' table is created in my local db as expected.
Is there another configuration setting that I'm missing in order to get sinatra-authentication to properly look for the erb templates rather than haml files. Any help would be greatly appreciated.
Thanks
The specs don't test that the template_engine setting works, and looking at the way the setting is called, I believe it's not correct, i.e.
send settings.template_engine, get_view_as_string("index.#{settings.template_engine}"), :layout => use_layout?
might better work as:
send app.settings.template_engine, get_view_as_string("index.#{app.settings.template_engine}"), :layout => use_layout?
that's what I reckon. If you fork the project, change the line and add it to your Gemfile and it works then consider writing a quick spec for it and you'll have improved the mainline of that project as well as fixed your problem.

no such file to load -- map_by_method

This question was asked before here, but can't say that the answer helps me. I am using Rails 3.1.3. When I run rails console on my local dev machine, I get the following message:
no such file to load -- map_by_method
The message doesn't prevent the irb session from launching, so it's benign. But I'd like to get rid of it. At one point in time I had the map_by_method gem installed, but I removed it from the Gemfile and gemset -- yet the message still appears. Any idea how to vanquish it?
there might be some causes for this:
there might be some other gem which has it as a dependency
you might have a require 'map_by_method' in your code
you might have a require in your .irbrc
the .irbrc can be located in your user home or in the current working directory.
have a look at an example .irbrc here: http://matthewhutchinson.net/2010/9/19/rails-3-bash-aliases-and-irbrc-configs
Probably the gem map_by_method has done some permanent changes on your system. Try re-installing it. It should fixed your problem. Same thing happened to me once. If it doesn't, try specifying it in development section of gemfile.

Heroku + Haml Problems

I am having issues with Heroku and Haml, I am able to run my app on localhost no problems, all test pass to, however when I go to run it on Heroku I get the following error:
We're sorry, but something went wrong.
We've been notified about this issue and we'll take a look at it shortly.
I read another post on Stackoeverflow that basically said to add a .gems file and add:
haml --version '>= 2.2.0'
I did that and I'm still having the same problem, so I'm wondering what I am doing wrong.
Update: I fixed that problem had to do with cache - and Heroku being read-only however now the theme I've selected via web-app does not load up on the Heroku page it shows up on local host however correctly. I looked at the log file for Heroku and it doesn't show any errors, so is it another permission issue?
Here is the log file - https://gist.github.com/1173667
Thanks,
Looks like your stylesheets are not included as part of the layout.
Assuming your stylesheet is available as public/stylesheets/styles.css, try adding the following line inside the head tag in application.html.haml
= stylesheet_link_tag 'styles.css'
That should resolve the theming issue. If not, post the code in application.html.haml
UPDATE:
From the logs, looks like you have two layouts: layouts/sign and layout/application. If they are there for a reason, you need to address that.
Else, change your home controller to render the new layout:
class HomeController < ApplicationController
layout "sign"
end

Multiple public folders, single rails installation

I have a rails application I would like to use for multiple sites, each with different designs.
I would like to change the rails installation /public directory to something else (dynamically eventually). However, I have run into a problem (bug?) changing directories...
In my application.rb file I change the paths.public path to something other than "public" (let's say "site_one"). Here is the code:
puts paths.public.paths
paths.public = "site_one"
puts paths.public.paths
The two "puts" commands are for debugging. Now run "rails s" and you will see:
/home/macklin/app/public
/home/macklin/app/site_one
This verifies the path is changed correctly. However, shortly afterward, rails throws the following error (let me know if you need the full trace):
Exiting
/usr/lib/ruby/gems/1.8/gems/railties-3.0.3/lib/rails/paths.rb:16:in `method_missing': undefined method `javascripts' for #<Rails::Paths::Path:0x7f422bd76f58> (NoMethodError) from /usr/lib/ruby/gems/1.8/gems/actionpack-3.0.3/lib/action_controller/railtie.rb:47
My guess is it cannot find the javascripts directory even though it is clearly sitting in the "site_one" folder.
Does anyone know why I am getting this?
I know this question is pretty old, but I think I found an answer for this in Rails 4.2.
You just simply have to put this line in your config/application.rb:
middleware.use ::ActionDispatch::Static, "#{Rails.root}/another_public_folder_name", index: 'index', headers: config.static_cache_control
This makes all files in /another_public_folder_name to be served by Rails.
This is the way Rails use to setup the standard /public folder. I found it checking the sources:
https://github.com/rails/rails/blob/52ce6ece8c8f74064bb64e0a0b1ddd83092718e1/railties/lib/rails/application/default_middleware_stack.rb#L24
Duh. Just add 2 more rules for stylesheets and javascripts (I guess they get wiped when you change the parent path)
paths.public.stylesheets = "site_one/stylesheets"
paths.public.javascripts = "site_one/javascripts"
